Brother HL1020 background bands

The onset of this was quite sudden: near the end of the toner cartridge's
life, dark horizontal background bands started printing on my laser Brother
HL1020. I opened the drum unit (DR300) and cleaned out excess toner, and
replaced the cartridge with an original Brother TN300. The bands are now
lighter, but still there. Several thin vertical white lines interrupt the
bands. I noticed that when the printer has been just turned on, the bands
are very light, and get progressively darker with each page. When I print
text, the characters have a sort of white shadow on the dark bands under
them, like an embossed effect.
What can I do? I can't really afford a new drum unit right now. If that's
the problem, can I repair the drum unit? Where do I find parts? Or are
rebuilt drum units worth it?
 
I opened the drum unit again, and the rubber roller that transfers toner to
the OPC drum has what look like wear marks, and they appear to correspond
to the dark bands in shape. Can I repair this roller somehow? Or replace
it -- where would I look for one? It seems crazy to replace the whole drum
unit for one worn roller.
